VULCANIZER.

Specification of Letters Patent.

Patented Get. 5, EH5.

Application filed October 6,1914. Serial No. 865,353.

To all whom it may concern:

Be it known that I, FRANK L. GIBSON, a citizen of the United States,residing at Pender, in the county of Thurston and State of'Nebraska,have invented certain new and useful Improvements in VulcaniZers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to vulcanizers and the primary object of theinvention is the provision of a device of this nature which has avertically operable cup and a pivoted lever provided with a cam formedintegral therewith for raising or lowering the vulcanizing cup. 7

Another object of this invention is the provision of a base board whichis pivotally mounted upon the base plate of the vulcanizer so that itmay move in opposite direction. I

lVith the foregoing and other objects in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in theaccompanying drawings and claimed.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters designate like orcorresponding parts throughout the several views, and in which 11-Figure 1 is a side elevation of the i1n proved vulcanizer. Fig 2 is acentral sectional view through the vulcanizer. Fig. 3 is a front view ofthe vulcanizer, and Fig. 1 is a cross sectional view showing thevulcanizing cup in plan.

Referring more particularly to the drawings, 1 designates the supportingstructure of the vulcanizer which has a base :3 formed thereupon. Thebase 2 projects forwardly from the main body portion 1 of the vulcanizerand it has upstanding ears 3 and d formed thereupon, which ears areprovided with recesses 5 formed therein. The recesses 5 which are formedin the ears 3 and 4t receive the pins 6, which are formed integrallywith the sides'of and substantially equi-distant of the ends of a plate7. By seating the pins 6 in the slots or recesses 5 the plate 7 will bepivotally supported above the forwardly extending extension 8 which isformed on the base 2. The plate 7 which is provided for receiving a tire(not shown) or like article which is to be patched or vulcanizedthereupon, has positioned directly thereabove a vulcanizing cup 9. TheVulcanizing cup 9 has a plurality of vertical pins 10 formed therein andextending upwardly within the retaining portion of the same, forincreasing the heating area of the cup, so that when any suitable typeof volatile liquid is placed within the cup and ignitech the cup will beeflicie-ntly heated for vulcanizing or patching a tire.

The cup 9 has a pair of rods 11 secured thereto which rods extendupwardly therefrom and are slid-ably seated in openings 1.2 which extendthrough the forwardly extending arm 13. The arm 13 is formed upon thesupporting structure 1 of the vulcanizer and it has secured to its sidesand extending upwardly therefrom plates 11 and 15. The plates 14 and 15are positioned upon opposite sides of the forwardly ex tending arm 13 asis clearly shown in Fig. 3 of the drawings, and they have pivotallymounted therebetween a lever 16. The lever 16 is pivotally mounted upona pin 17 which extends through the plates 14 and .15 adjacent the upperends of the same. The lever 16 has a cam 18 formed upon the lower sideedge of its pivoted end. The cam 18 is provided with a cam shapedopening 19 formed therein, in which is seated a roller 20. The roller 20is rotatably mounted upon a pin 21. The pin 21 is carried by arms 22 and23, which depend therefrom and are pivotally connected as at 24: to thehead block '25 of the vulcanizing cup structure. The head 2-5 has bores26 extending horizontally thereinto from the ends of the same.

In the operation of the improved vulcanizer heretofore described: \Vhenit is desired to vulcanize or patch an inner tube (not shown) the cup 9is filled with kerosene oil, gasolene, or analogous volatile liquid andthe same is ignited, which thoroughly heats the cup 9. The tire is thenplaced upon the pivoted plate 7 and the lever 16 is operated for forcingthe head 9 downwardly and into engagement with the tire. The heat passedoff by the heated cup 9 will properly vulcaniz'e the tire. The cup 9 israised from. engagement with the upper surface of the plate 8 by theupward movement of the lever 16, which moves the head 2-5 through theconnection between the cam 18 and the head through the medium of thearms 22 and 23. The roller 20 which rides within the cam shaped opening19 is provided for relieving the friction contingent with the operationof the lever 16. In pressing the lever 16 downwardly, the outer surfaceor periphery of the cam 18 rides upon the upper surface of the head 25and forces the head 25 and the cup 9 which is connected thereto throughthe medium of the rods 11 downwardly.

From the foregoing description taken in yonnection with the accompanyingdrawings the advantages of the construction and is of the method ofoperation of the improved vulcanizer will be readily apparent to thoseskilled in the art to which this invention apprehended within the scopeof what is claimed.

What is claimed is 1. In a vulcanizer, a supporting structure having abase formed integrally therewith and extending forwardly therefrom,upstanding ears formed upon said base, said ears being provided withrecesses formed in their upper ends, a plate having pins formedintegrally therewith, said pins being seated in said recesses forpivotally supporting said plate upon said forwardly extending section ofsaid base, and a vulcanizing cup positioned upon said pivoted plate formovemlent into or out of engagement with said p ate.

2.
